Coffee (Coffea L.) belongs to the family Rubiaceae and is a main cash crop for tropical farmers. It has more quantity of medicinal value and protein (25–28%). As an environmentally sensitive crop, climate change has a significant impact on the quality and stable production of coffee. To develop abiotic baroreceptors on the tolerance response in coffee, tremendous research is going on to improve the productivity under varying degrees of stress at various growth stages. Physiological, morphological and biochemical parameters change the productivity and quality of coffee. This paper reviews some of the important aspects of biotic and abiotic tolerance in coffee. We explain the best implementation methods for the improvement of coffee production and briefly advantages or importance of coffee in medicinal values, significances of biotechnological aspects and genetic engineering approaches for crop improvements.

The purpose of the study was to determine the effect of joint mobilization with respiratory muscle taping on pulmonary function and chest expansion ability in patients with chronic stroke. Thirty subjects (n=30) were randomly divided into three groups: a joint mobilization group (n=10), a respiratory muscle-taping group (n=10), and a joint mobilization with respiratory muscle-taping group (n=10). Measurements for pulmonary function and chest expansion were performed to assess its effectiveness. A spirometer was used to measure the pulmonary function, and a tape measure was used to assess the chest expansion. In the joint mobilization group, peak expiratory flow (PEF) was increased. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and upper and lower chest expansion were also increased. All of variables of respiratory muscle-taping group also were increased. FEV1 and FVC were significantly different between joint mobilization with respiratory muscle-taping and respiratory muscle-taping group. The results of the present study suggest that mobilization with respiratory muscle taping increase the pulmonary function and chest expansion.

In the present study, we analyzed ecological functional groups of diverse hymenopteran families from five different vegetation stands in the Gwangneung forest. Hymenopterans were collected using three different traps from March to October 2015. Pollinators were a dominant group from March to May and declined significantly after that period. Parasitic group made major peaks from April to May and made another small peak in August. Predatory group reached to a peak in April and July respectively but appeared to be active even in October when all the other groups mostly disappeared. The vegetative communities were ordinated with the hymenopteran family assemblages using the Nonmetric multidimensional scaling (NMDS). The result of NMDS analysis showed that the community structure of the hymenopteran functional groups from the Quercus rubra stand is different from those of the other stands.

HyPer is the genetically encoded biosensor of intracellular hydrogen peroxide (H2O2), the most stable of the reactive oxygen species (ROS) generated by living cells. HyPer has a high sensitivity and specificity for detecting intracellular H2O2 by confocal laser microscopy. However, it was not known whether high speed ratiometric imaging of H2O2 by HyPer is possible. We thus investigated the sensitivity of HyPer in detecting changes to the intracellular H2O2 levels in HEK293 and PC12 cells using a microfluorometer imaging system. Increase in the HyPer ratio were clearly evident on stimulations of more than 100 μM H2O2 and fast changes in the HyPer ratio were observed on ratiometric fluorescent images after H2O2 treatment. These results suggest that HyPer is a potent biosensor of the fast temporal production of intracellular H2O2.

Diffuse involvement of the right pulmonary artery (PA) associated with fistula between the PA and coronary artery is report-ed in a woman with Takayasu’s arteritis. Both the subclavian arteries were totally occluded and drained by the meanderinged artery arising from both common carotid arteries. Lung perfusion scan revealed perfusion defect of right lung. Two fistulas were identified. A large fistula was between the right PA and left circumflex artery. A small fistula was between the right PA and left anterior descending artery. This is a rare case of Takayasu’s arteritis presenting with a coronary – pulmonary artery fistula that is secondary to a diffuse unilateral involvement of PA.
